Position of Muscle Caveolae
</h2>

<h3>Description</h3>

<p>The <code>cav</code> data frame has 138 rows and 2 columns.

with sides of length 500 units.  This grid was originally on a 2.65mum
square of muscle fibre.  The data are those points falling in the lower left 
hand quarter of the region used for the
dataset <code>caveolae.dat</code> in the <span class="pkg">spatial</span> package by B.D. Ripley (1994).
